Soyuz MS-28, Russian production No. 759 and identified by NASA as Soyuz 74S, is a planned Russian crewed Soyuz spaceflight to launch from Site 31/6 at the Baikonur Cosmodrome no earlier than 27 November 2025 to the International Space Station.
The mission was slated to be the first to launch after the termination of a NASA/Roscosmos barter agreement, where one Russian cosmonaut flies on a NASA spacecraft in exchange for one NASA astronaut flying on a Soyuz. Consequently, as of 2024, this mission was scheduled to transport three Russian cosmonauts. However, NASA and Roscosmos were negotiating to extend their seat exchange program beyond 2025, and in April 2025, NASA announced that Christopher Williams had been assigned to the crew.
